You can do the above , or place your curser at the very top corner until a double arrow shows up. Left click on your mouse , while holding the left click button down , drag the arrow to the size you want. Release the button on your mouse.

It finally worked :lol: I have a laptop with no mouse, the scroll bar was not showing and every time I tried it turned blue. i couldn't see the responses because it would go down. Thanks alot everyone for your help.
